  1201B Specifications






  Model 1201B/C GNSS Synchronized Clock (100ns)
  Built by Power Professionals, For Power Professionals
The Arbiter Systems® Inc. The 1200B GNSS Synchronized Clock is a multi-satellite system (GPS/GLONASS/Galileo/BeiDou) timing source for precision timing applications. Arbiter's next-generation sub-station clock provides enhanced performance and security (EPS) while supporting the standard outputs and popular options of our existing clocks.

EPS benefits include multisystem timing sources, standard hold-over oscillator, multiple levels of security, secure communications, and anti-spoofing technology. The Model 1201B/C is compatible with Arbiter-Systems earlier clock models, supporting the same legacy options and outputs, while enabling the transition to a more secure device.
